TUSB9261 SPI Flash Memory Map

Hello Rob,

The 8-bit checksum is just a sum of all the data in a block into a single byte.

As you have already mentioned, figure 3-1 on the FlashBurner user´s guide describes the memory allocation withing the Flash.

First 2 bytes (at address 0x0000) must contain 0x9260 as a signature to identify a valid firmware.
Followed by a 1 byte identifier containing 0x01 to indicate the upcoming data contains the descriptors information.
Then 4 bytes indicating the length of the descriptors data.
Then the descriptors data itself
And 1 byte for the 8-bit checksum of the descriptors data.
Finally, a 1-byte identifier containing 0x02 to indicate the upcoming data is the firmware data
Followed by 4 bytes containing the length of the firmwae data.
The Firmware data itself
And 1-byte for the 8-bit checksum of the firmware data.

I would like to mention that we also have a command-line version of the FlashBurner utility that might be more suitable for an automation proccess. Let me know if that's what you are looking for.

Regards,
Jorge.

Thanks Jorge, that's all really useful information.

The command-line version of FlashBurner is definitely of interest - are you able to provide a copy of this?

Regards,

Rob

I've just un-verified this answer, not because it's wrong, but because I still have an outstanding question from your reply which I didn't want to be overlooked:

How can I get hold of the command line version of Flash Burner?
